Tail of the Dragon on Discovery Channel

Discovery channel had a show on last night called Hell0 Roads. It had about 5 min. piece on the Tail of the Dragon (US129 NC/TN). Nothin' great but showed several crashes happening. It will be on again Sat. and Sun.

I watched that with nothing short of awe. I can just picture me riding along on that road with my nice bike coming around a corner and seeing an 18 wheeler taking up the entire road because they're too big to negotiate the corner on just their side. For the life of me I can not understand why the authorities have not addressed this simply by banning big rigs from such a narrow, curvy roadway.
